« Tu as des frères et sœurs ? » is guaranteed first-conversation material. Here’s the whole family tree — including the famous belle-mère trap.
The quick version — the full lesson is below. More shorts →
French uses ONE prefix for both in-laws and step-family: la belle-mère = mother-in-law or stepmother; le beau-père, le beau-frère, la belle-sœur — same double duty. Context decides, and nobody finds it ambiguous but you. Bonus: les beaux-parents = the in-laws.
At home, nobody says l’oncle et la tante — kids say tonton and tata. Parents call their children les gosses or les gamins (the kids) — though be careful: in Quebec, gosses means something else entirely, so say les enfants over there. And a favourite between couples: ma moitié — my other half.
— Tu as des frères et sœurs ?
— Oui, j’ai un grand frère, il habite à Lyon. Et toi ?
— Moi, je suis fille unique. Mais j’ai plein de cousins !
— Nous, on est quatre. Les repas de famille, c’est le chaos.
Note the pattern: un grand frère, une petite sœur — big and little is how people actually say older and younger (l’aîné and le cadet are the tidier pair you met above). And on est quatre — there are four of us — is how the French count themselves. Bounce every question back with Et toi ? and you sound like a local.
Before a vowel, ma becomes mon for the sound: mon amie, mon école. It’s still feminine — the possessive system is unpacked in mon, ma, mes.
Grand-mère — grand stays short in the family words, with a hyphen: grand-mère, grand-père, grands-parents. Gender logic for everything else lives in le or la?.
The full script — name, origin, family, job — is in introduce yourself in French.
